Steps to reproduce:

1. Update Zabbix Agent 2 to version 7.0.0
2. Host are pointed at proxy groups in active mode
3. Assign Template "Windows by Zabbix agent active" version "Zabbix, 6.4-0"
4. Wait some random amount of time...
5. Agent logs start repeating "no active checks on server [PROXY_ID:PORT]: host [HOSTNAME] not found"
6. Windows service shows agent is still running but agent activity halts and no data is sent to proxy/server
7. Restarting the agent resolves the issue 

Result:
See attached log file.
Actual proxy ip address/port and host hostname replace with PROXY_IP:PORT and HOSTNAME.
Expected:
Zabbix agent does not randomly freeze on Windows hosts
